Chromosome pairing relationships within cultivated potato (Solanum tuberosum) and its wild tuber-bearing relatives (Solanum sect. Petota) have been interpreted by genome formulas, developed in the early 1900s, through techniques of classic meiotic analysis of interspecifi c hybrids. Here we reexamine potato genome hypotheses with the fi rst phylogenetic analysis of all major genomes of sect. Pe...

In this study, six taxa of micromycetous fungi collected from Golestan province (N Iran) during spring and summer of 2010, are reported. Melanospora zobelii on Picoa lefebvrei, Diachea leucopodia on Sambucus nigra, Choanephora cucurbitarum on Brassica oleracea, Trichurus spiralis on Prunus domestica, tuber of Solanum tuberosum and seeds of Gossypium hirsutum and Dictyosporium heptasporum on dea...

We examined the antioxidant effects of polyphenol/anthocyanin-rich potato (Solanum tuberosum cv. Shadow-Queen) flakes in male rats fed a high-cholesterol diet. The rats were served either a high-cholesterol (0.5% cholesterol plus 0.125% sodium cholate) diet, or a high-cholesterol diet containing a mixture of 243 g alpha-maize starch/kg supplemented with one of the following (per kg diet): 300 g...

In the present study, we reviewed food poisoning data published by the Ministry of Health, Labour and Welfare of Japan from 1961 to 2010 in Japan to analyze the trends of plant toxin food poisonings (PTFPs). The annual number of incidents of PTFPs has gradually increased since 1995. PTFPs were predominantly caused by Datura spp., Veratrum spp. and Aconitum spp. Although PTFPs frequently occurre...

Recent advances in -omics technologies such as transcriptomics, metabolomics, and proteomics along with genotypic profiling have permitted dissection of the genetics of complex traits represented by molecular phenotypes in nonmodel species. To identify the genetic factors underlying variation in primary metabolism in potato (Solanum tuberosum), we have profiled primary metabolite content in a d...

A Mexican hexaploid wild potato species, Solanum demissum (dms), was only used as a female in previous breeding programs. The resulting clones with dms cytoplasm produced abundant, but non-functional pollen. A 170 bp DNA fragment, named Band 1, was originally detected in the F(1) hybrid between dms and S. tuberosum. In this study, the sequenced region was extended to 1,032 bp; nevertheless, it ...

The majority of disease resistance (R) genes identified to date in plants encode a nucleotide-binding site (NBS) and leucine-rich repeat (LRR) domain containing protein. Additional domains such as coiled-coil (CC) and TOLL/interleukin-1 receptor (TIR) domains can also be present. In the recently sequenced Solanum tuberosum group phureja genome we used HMM models and manual curation to annotate ...

We isolated and identified AHL-degrading bacteria from the leaf surface of Solanum tuberosum. The 16 isolates inactivated both short- and long-chain AHLs. Two of these isolates, identified as Microbacterium testaceum, showed putative AHL-lactonase activity. These two strains interrupted quorum-sensing dependent bacterial infection by plant pathogen Pectobacterium carotovorum subsp. carotovorum....

Segregation of restriction fragment length polymorphism (RFLP) loci was monitored to determine the degree of homeologous pairing and recombination in a hexaploid somatic hybrid, A206, the result of protoplast fusion between Solanum tuberosum (PI 203900, a tetraploid cultivated potato) and Solanum brevidens (PI 218228), a diploid, sexually incompatible, distant relative harboring several traits ...
